MAIL-TRANSFERRING DEVICE.

Specification of Letters Patent.

Patented Aug. 1, 1916.

Application filed J nne 23, 1914. Serial No. 846,880.

To all whom it may concern:

Be it known that I, HARRY S. OLGARD, citizen of the United States, residing at Cooperstown, in the county of Griggs and State of North Dakota, have invented certain new and useful Improvements in Mail Transferring Devices, of which the following is a specification.

My invention relates to devices for transferring mail from a stationary support to a moving train or vice versa.

As its primary object, the invention contemplates mail support means, so constructed as to be actuated by the engagement of receiving means therewith, such engagement providing for an instantaneous. release and an automatic transfer of the said mail matter from the support to the receiving means.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation of a mail car equipped with my improved receiving and delivery apparatus; Fig. 2 is an enlarged longitudinal sectional view of the mail bag support or delivery means; Fig. 3 is a sec tion on the line 5 5 of Fig. 1; Fig. ll is an elevation of the ring; and. Fig. 5 is a fragmentary sectional view of the receiving means.

Referring now to the drawings by numerals, 1 designates a mail car open adjacent each end as'indicated at 2, the said mail 1 car being provided at one end with a platform 3 upon which the receiving means, car-.

ried by the car, is mounted.

As shown to advantage in Fig. 1, the receiving means mounted upon the car is disposed in a plane slightly below the plane of the delivery means forming a part of the stationary support designated as an entirety by the numeral 4; and that the delivery means mounted upon the car is disposed in a plane below the plane of the receiving means of the car, but in a plane above the receiving means of the stationary support designated as an entirety by the numeral 5, the said two stationary supports designated respectively land 5 being spaced apart a predetermined distance whereby to coact respectively with the receiving and delivery means of the car. The receiving means of the car and the receiving means of the stationary support being the same in construction, the construction of but oneof the said means will be described in detail, the reference numerals being applied to both. The delivery means of the car and the delivery means of the support are also in duplicate, therefore, as above suggested, the reference numerals applied to one means may equally as well be applied to the other. i

In its preferred embodiment, .the delivery means consists of an angle arm or crane'o, longitudinally recessed as indicated at 7 Operating within recess 7 is a locking rod or member 8, to one end of which is pivoted as at 9 a trip arm or lever 10 fulcrumed adjacent the pivot point-9 within the recess as indicated at 11, the said trip arm extending, as shown in the drawings, in such relation to the receiving means as to be engaged by a lug or projection 12 forming a part thereof. The free end of rod 8 extends across a recess 13 formed in the end of the arm 6, said recess 13 being open to the recess 7 as indicated at 1 1. Recess 13 is preferably polygonal and, previous to a mail transferring operation is adapted to receive the shank 15 (polygonal in cross section) of a mail bag supporting ring 16, the said shank having an opening 17 formed therein, the opening receiving the free end of the rod 8 as shown in Fig. 4, the rod serving as a means whereby the ring is held immovable relatively to the arm 6 until the said rod is withdrawn from engagement with the shank by actuation of trip arm lever 10.

Ring 16 is made sectional, the sections being designated respectively 18 and 19, the latter section being pivoted as at 20 to the section 18 and detachably fastened as at 21. By constructing the ring, as noted above, it is apparent that the mail pouch or matter acted upon may be fastened to the ring by first disengaging the section 19 at the point 21.

As a means whereby rod 8 is normally held in a position whereby to extend into the recess 13, I provide a spring 22, the spring. embracing the rod and abutting at one end a collar or flange 23 thereon and at its opposite end'an enlargement 24 of the arm 6 extending into the recess 7. The de livery means mounted upon car 1 is so mounted as to be movable towardmnd away from one of the openings or doors 2 thereof, a lever 25 operating in connection with a segment 26 serving as a controlling means therefor. Lever 25 is connected to arm 6 by a rod 27 The delivery means of the ,car, particularly the arm 6, is mounted for movement toward and away from the car or into and out of operative position. The delivery means or lever =6, forming a part of stationary support member 4: is mounted upon a vertically disposed shaft 29 turnable relatively to the support to provide for movement of the said means into and out of operative position.

As above set forth, the receiving means mounted upon the car is positioned at the opposite end thereof from that .of the delivery means, the said receiving means of the car operating in conjunction with the delivery means forming a part of stationary support 1, while the receiving means forming a part .of stationary support 5 operates in conjunction with the delivery means of the car. Said receiving means, consists of an angle arm 30 having a recess 31 formed therein adjacent its free end, said recess having pivoted therein as at 32 a retaining element '33 normally held at an angle to the arm through the medium of a spring 3 1 at all times exerting upward pressure thereupon. Lug or projection 12, above referred to, is carried by the receiving arm, said lug being disposed at a point adjacent the bend in the arm to engage the trip or lever 10 forming a part of the delivery means to in this manner release and automatically transfer the mail matter from the said delivery means thereto.

The arm 30 mounted upon the car is movable toward and away from the other of the said openings or doors 2 therein, such movement being controlled by a lever 35 having associated therewith a segment 36, said lever being connected to the arm by a rod 37 in much the same manner as the arm." 6 is connected to lever 25. The arm 30 of the receiving means carried by the stationary support 5 is mounted upon a vertical shaft 39, the said shaft being rotatable to provide for movement ,of the said arm into and out of operative position as occasion may demand.

To provide for an instantaneous release of the ring 16when unlocked through movement of rod 8 a spring 40 is disposed in the recess 13 of arm 6, the spring abutting at one end of the head 41 of a pin 42 and at its opposite end, one of the recess walls, said spring normally exerting an outward pressure upon the head 41. To limit movement lugs 12, forming a part of the receiving means, engage the trip or lever 10 of the respective arms 6, such engagement causing the rod 8 to be withdrawn against the tension of the respective springs 22, this action causing the supporting rings 16 to be simultaneously released. The moment the rod 8 is actuated, the tension of the respective springs 40 is sufiicient to cause the said supporting rings to be ejected, said rings being then directly engageable with the receiving arms upon which they are retained, retaining element 33 preventing accidental removal of the rings in one direction, and the angular extension of the said arm 30 preventing accidental removal of the said rings in the opposite direction.

From the foregoing, taken in connection with the accompanying drawings it will be noted that the operation of the device or apparatus is simple, positive, and efficient; that the delivery means is readily accessible to the mail car attendant, said means being movable relatively to the car through actuation of lever 25; and that the receiving means of the car is also readily accessible to the car attendant, said receiving means being movable relatively to the car through actuation of lever 35.

In reduction to practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claims.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent, is

1. {In a mail delivery apparatus, a support arm provided with a longitudinal recess, a partition, a rod extending longitudina'lly of the recess and fitting a slot therefor in said partition, ayfiange upon the rod, a support element for the mail bag acted on,

said element fitting a socket therefor in the arm, .a spring arranged to embrace the rod and to abut respectively the flange and the partition to releasably lock said element in engagement with the arm, means having connection with the rod to withdraw it from engagement with said element, and a spring engaging the element to forcibly eject it when released.

2. In a mail delivery apparatus, the combination with the support element for the mail bag acted on, said element being provided with a shank, of an arm having a socket formed therein and into which the shank extends, means to releasably lock the shank and the arm, and a -spring arranged within the socket to abut respectively the shank and the socket walls to forcibly eject the element when released, and means to release said element.

In testimony whereof I aflix my signature in presence of two witnesses.
